FLUSH-TANK.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed December 22, 190B. Serial No. 349,094.

T0 all whom it may concern.

Be it known that I, WYILLIAM L. REED, a resident of Pittsburg, in the county of Alleghe/ny and State of Pennsylvania, have invented certain new and useful Im rovements in Flush-Tanks, of which the fo lowing is a specification.

This invention relates to flush tanks for closets, and one object is to Aarrange the Hush discharge or out-let in the lane of, orat .least no higher than, the bottom of the tank, sothat each time the closet is flushed the tank Will be fully emptied and drained, thus keeping it clear of sediment Whichaccumulates in tanks of present design wherein the flushing outlet is above the plane of the tank bottom.

A further purpose is.to provide a flush tank With a raised cover which forms a iloat space at the top of the tank so that practically the entire depth of the latter may be utilized for Water.

A further improvement consists in forming the cover Without a back so that it may be fitted tothe tank with the back of the latter bearing against a wall or other support to which is is secured. The ,open back also affords the necessary airl inlet for the tank. Also in connection With the cover, I provide improved means for holding the backless cover against vforward movement so that it can be removed only by being lifted from the tank.

Still a further Aobject is to form a 'ilsh tank of sheet metal pressed into the requisite shape, and further, to form the bottom of the tank With a pressed depressionto receive the ilush valve mechanism so that the flush outlet may be noA higher than the planeof the tank bottom.

In the accompanyin drawings Figure l is ayertical longitudine. sectional .view of a pressed metal tank constructed'in accordance lwith the invention. cFig. 2isa top planvievv, partly in section. ZFig` 8 is a vertical cross-sectional 1Jievv on lineB-B of Fig. 2. 4 is an end viexv ofa portion of 'the tank and cover.

eferring tothe drawings, the Atank 2 is shown of'oblong shape, with its rear side 3 bearing against and secured by screwl 4 to `a wall 'or other upright support 5. The

outlet of the flush valve above the plane of the tank bottom, the result being that the tank is never fully 'drained and much sediment accumulates therein. To obviate this, I form tank bottom 7 With a depression 8, which, in the y referred or pressed tank here shown, is orrned by pressing, as will be understood. The upper ortion of this depression has a surroun ing offset or shoulder 9 which forms a seat for flange 10 of fitting 11, vwhich latter carries the flush valve-seaty or outlet 12 Vand overflow pipe 13. Flange 10 tting 4the depression offset in connection with an interposed gasket or Washer forms a seal, preventing any Water or sediment from passing into depression 8. Fitting 11 may be secured by clam ing 'nuts 14 of usual form. It Will be note that the flush outlet 12 is inthe plane of tank bottom 7, and hence each time the flush is operated the tank is fully drained and all sediment carried therefrom. It is only essential that the Hush outlet should not be above the plane of the tank bottom; it lmight be somewhat lower than the same Without departing from the invention. The mechanism for operating Hush-valve 15 is not shown as it orms no part of the invention.

Inlet valve 16 may be 'of the usual'or any preferred construction, being operated by an 4arm 17 and float'lS in the customary Way. Heretofore, it has 4been usual to construct the tank body of such height as to afford room at thetop for the float when in elevated position. In my improved tank, I utilize practically its ventire depth for `water, the normal level thereof reaching nearly to the top as shown, and provide thetank with a raised top to afford the necessary inclosed space for the float.

'This arrangement effects a saving in cost,

and enables me to secure Without diiculty a' pressed` metal tank of suflicient. depth.

The raised cover 19 vis provided at the front and opposite ends With the depending flange or skirt 20, which extends down over the exterior of the tank in lid fashion. The cover is however formed without a back, one purpose of such formation being to fit the cover accurately against the tank `supporting surface 5, andanother purposev is to rovide the necessary air inlet. To hold the cover in placethat is, to prevent it from moving frontward or laterally `on the tank, skirt 20 is forrned'with inward .20 prevent the cover from moving frontward.

bulges which when the cover is in place,

thus holdingr the cover quite as securely as though the skirt Were extended around the rear side of the tank.

hile I have shown and described the preferred construction and arrangement of the several features of the invention as applied to flush tanks, some or all ofsaid eatures may he applied to tanks yorv vessels of other kinds Without departing from the spirit and scope of the appended claims.

I claim. K

l. The combination of a rectangular tank having its end faces formed to receive prof jections on a cover, a cover having a flange depending from itsI front and ends, and inward projections on the end portions of the iiange adapted to engage the tank ends and 2. The combination of'a rectangular tank having rounded rear corners, a cover having f a flange depending from its front and ends7 and inward projections on the end portions of the iange adapted to engage said rounded corners and prevent the cover from moving frontward.

3. The combination with a flush tank adapted to be secured to a Wall or other support, the tank having rounded rear corners, of a raised cover fitting the tank and Wholly open at its rear side, the cover having a flange depending from its front an ends, the end portions of the flange being bent inward to engage the rounded corners of the tank and prevent the cover from moving forward.

In testimony whereof I aix my signature in presence of two Witnesses.
